3. INSTALLATION
The following is a quick guide to installing and setting up the driver: All you need is an AC power
source, a signal source, a loop pair (or single loop cable) and a loop layout drawing. See ‘Designing
Induction Loops’ handbook available from the Ampetronic website or contact Ampetronic for advice .
Location
The unit may be free standing or 19” rack mountable using the rack ‘ears’ supplied . Fitting of the
‘ears’ is achieved by removing the three forward most screws on both sides . The same screws
are then re-used to secure the ‘ears’ in place. (A PH2 screwdriver will be required). For 19” rack
mounting the four rubber feet must be removed .
The location must provide adequate ventilation for the unit .
Internal fan provides forced ventilation using air vents at the front (intake) and rear (exhaust) of the
unit . These vents must be unobstructed for satisfactory cooling . If the unit is installed in an enclosed
environment, sufficient airflow into the enclosure must be provided through vents, fans or other
means, such that the units exhaust air is not recycled to the inlet - causing a reduction in output
current and triggering the error LED to flash and an error message to be displayed.
Contact Ampetronic for advice on cooling requirements for your installation .
a . Rack mounting - remove the front 3 x 8mm securing screws on each side of the driver and
secure the supplied rack mounting ears using the same screws
b . Insert the driver into the 19” rack unit space and secure to the rails using 4 x 3/4 inch (19mm)
screws and washers which should be supplied fitted to the rack unit
c . Affix loop twisted pair to Nuitrik NL2 connectors (supplied) or quad core loop feeder cables to
Nuitrik NL4 Connector and insert into Output Channel A/B sockets on the rear of the driver
